Thread: serial grows on failed requests

serial grows on failed requests

Hi, my table is defined as:
CREATE TABLE users (
     id integer NOT NULL,
...
);

CREATE SEQUENCE users_id_seq
     INCREMENT BY 1
     NO MAXVALUE
     NO MINVALUE
     CACHE 1;

ALTER SEQUENCE users_id_seq OWNED BY users.id;

Although it's just a more verbose way to say
create table users (id serial primary key);
:)

When I do an insert that fails (like FK inconsistency, illegal value,
etc.) the users.id grows nonetheless... This is unacceptable for my
current needs. Any way to prevent that while still maintaining ease of
use? Using PostgreSQL 8.2.4

Thanks.
